Analysis of Earth's geologic record can reveal how the climate has changed over time. As profiled in the Science Bulletin below, scientists in New Zealand are examining samples from the rocky landscape once dominated by glaciers and employing a new technique called surface exposure dating, which uses chemical analysis to determine how long minerals within rocks have been exposed to the air since the glaciers around them melted. Comparisons of this data with other climate records have revealed a link between glacial retreat and rising levels of carbon dioxide in the air, findings that are informing scientists' understanding of global climate change today.

Many organisms use light to lure prey or draw attention, but scientists have found an octopus and a squid that use it to hide. The video below, created by the Museum’s Science Bulletins, shows how these deep-sea cephalopods fool their predators using bioluminescence. To learn more about the diversity of bioluminescence across the tree of life, visit the special exhibition Creatures of Light: Nature’s Bioluminescence.

Over the next two weeks, a team from Science Bulletins, the Museum’s multimedia online and exhibition program, will visit Peru to film a short documentary about protecting potato biodiversity in the region. Producer Tania Van Bergen, who is traveling to Lima and to the Huancavelica region, will be sending photos and dispatches from her trip in the coming weeks.
